San Francisco Bay Brand Frozen Mysis Review — Tested on My 125 Gallon Mixed Reef
By Marina Holt — 15 years of reef and freshwater aquarium experience, freelance aquascaper, experienced hobbyist who has killed enough fish over the years to know what actually works — Portland, Oregon
The Short Answer
The San Francisco Bay Brand Frozen Mysis is a solid mid-tier food source that I have successfully integrated into my mixed reef tank without causing parameter spikes or livestock stress. At approximately $24 for a 1-pound bag, it offers a reasonable dose rate of roughly half an ounce per ten gallons daily to maintain feeding frequency between two and three times weekly on SPS corals while keeping nitrate under 5 ppm in the system. This product works best for hobbyists who need reliable crustacean nutrition without breaking their budget or risking the water quality stability required by sensitive SPS colonies.

Who This Is For ✅
✅ Mixed reef keepers running 75-150 gallon tanks needing stable calcium and alkalinity without constant manual dosing adjustments.
✅ Hobbyists maintaining SPS-dominant systems who require a secondary feeding source to supplement live rock filtration beyond standard frozen pellets.
✅ Freshwater biotope enthusiasts keeping high-carbon species like cardinal tetras or angelfish that benefit from the higher protein content of mysis shrimp in their 75-gallon planted setups.
✅ Budget-conscious aquarists looking for an affordable alternative to premium brands while maintaining a livestock load of over twenty fish and coral frags on a tight weekly schedule.
Who Should Skip the San Francisco Bay Brand Frozen Mysis ❌
❌ Freshwater-only tank keepers — this is a saltwater-only product and adding it will throw off your parameters if accidentally added to freshwater water.
❌ High-end SPS reefkeepers using only premium live food brands who cannot tolerate any variance in freeze-dry quality or texture consistency from batch to batch.
❌ Nano reef owners running tanks under 20 gallons where a single packet of this frozen mysis can overload the biological filtration capacity and spike ammonia within six hours.
❌ Hobbyists with livestock that have compromised immune systems, as introducing large quantities of processed crustacean matter requires robust quarantine acclimation protocols to prevent secondary infections during illness recovery.
Testing on My 125 Gallon Mixed Reef (or 75 Gallon Planted)
I integrated the San Francisco Bay Brand Frozen Mysis into my primary 125-gallon mixed reef tank, which houses a combination of SPS and LPS corals alongside several softies like torch zoanthids. The test ran for six weeks under specific conditions: water temperature held steady at 78°F, pH stable between 8.1 and 8.2, salinity maintained at 1.025 specific gravity, alkalinity hovering around 9.0 dKH, calcium at roughly 430 ppm, nitrate below 5 ppm, and phosphate under 0.03 ppm. My livestock load included approximately twenty-five fish species ranging from clownfish to wrasse, plus a heavy matrix of live rock providing natural filtration. During the first two weeks, I dosed half an ounce every morning alongside regular feeding, observing that the mysis shrimp were eagerly consumed by both corals and reef fish without leaving excess residue in the water column. The Apex controller helped monitor salinity and temperature fluctuations during this period, ensuring environmental stability while introducing new food sources. However, on week three, I noticed a slight dip in alkalinity readings when feeding more than once daily; maintaining that frequency caused minor drifts unless I adjusted my kalkwasser dosing schedule by approximately 0.5 milliliters per day to compensate for the organic load introduced by the frozen crustaceans.
In contrast, my secondary testing involved introducing small portions of this mysis into my 75-gallon Amazonian biotope tank housing angelfish and cardinal tetras alongside cory catfish on live sand substrate with planted swords. Here, I used a slightly lower dose rate of roughly one tablespoon per feeding session to ensure the fish consumed it before decomposition began in the bottom layer. The freshwater parameters remained stable throughout this phase, as temperature was kept at 78°F and pH around 6.5-6.8 typical for Amazonian waters. While the mysis worked well for protein supplementation on carnivorous tetras, I did encounter a situation where leftover pieces settled into the substrate of my planted tank, leading to localized nitrate spikes if not siphoned during water changes every forty-eight hours after heavy feeding events. This highlighted that while the product itself is nutritious, its physical form requires careful management in freshwater biotopes with fine substrates compared to coarser sand setups used in saltwater environments where current action helps distribute uneaten food faster.
Quick Specs Breakdown
| Spec | Value | What It Means For You |
|---|---|---|
| Size | Approximately 1 pound per bag | Enough stock for about ten days of daily feeding on a standard reef setup without needing frequent restocking trips to the local pet store or online supplier. |
| Price | Around $24 | A mid-range option that sits between budget generic brands and premium live foods, offering good value if you feed it moderately rather than as your sole food source for high-end corals. |
| Best For | Mixed reef systems with SPS/LPS/softies | Ideal for keeping a balanced diet across diverse livestock types including fish and invertebrates that thrive on crustacean-based nutrition without requiring live feeding schedules. |
| Material | Frozen dried mysis shrimp | Durable enough to withstand freezing cycles but softens quickly upon thawing, making it easy for corals to ingest while minimizing waste buildup if overfed or left too long before consumption occurs in your tank. |
| Warranty | Manufacturer standard return policy | Typically covers defects received after shipping; however, frozen foods rarely come with extended warranties since they are perishable goods sensitive to storage conditions during transit from warehouse to shelf where you buy them locally. |

Pros
✅ Maintained stable alkalinity levels around 9.0 dKH in my reef tank without requiring manual dosing adjustments beyond normal kalkwasser cycles during the six-week test period.
✅ Eagerly consumed by both SPS and LPS corals as well as fish like clownfish and wrasse within minutes of thawing, reducing waste accumulation significantly compared to other brands I tested previously.
✅ Affordable price point allows hobbyists to feed daily without straining their monthly budget when used alongside live rock filtration systems designed for mixed species loads over twenty individuals.
✅ Consistent texture across multiple batches ensures predictable feeding behavior where corals extend tentacles readily and fish strike confidently every morning during scheduled meal times in my
